Can a re-certification be created in a web server?

Details

Created: 20 November 2015

In order to be able to use the re-certification, the “Extension or renewal of certificate” option is offered in many web servers. Here, a new request is created which is then copied to the website in the relevant field. If your web server does not offer the aforementioned option, a new key, and therefore also a new request, must generally be created. Some additional programs such as Open SSL can create requests with an existing key.

Please take note of the relevant operating documentation, as parts of the procedures differ greatly from each other!
